Katie Price is reportedly reluctant to cut off ties with Jane Pountney.

The 35-year-old former glamour model has accused her close pal of 20 years of having a ''full blown sexual affair'' with her husband Kieran Hayler, but it's claimed the star is worried Jane may spill her darkest secrets if they ever stopped being friends.

A source said: ''Katie cannot imagine things going back to normal with Jane, but she's said she's not sure she can completely cut her out. Jane's been through a lot with her and knows every intimate detail. She's always acted like a bodyguard, as well as a shoulder to cry on. She's Katie's party pal and knows so many details that Katie doesn't want to become public knowledge.''

Pregnant Katie has been left devastated by the news her husband - who is the father of nine-month-old Jett and her unborn baby - had a seven-month affair with Jane, and after two previous failed marriages, the mother-of-four is ''inconsolable''.

The insider explained to Closer mgazine: ''Katie's been through so much, meeting Kieran seemed like everything was finally coming right for her. She saw them having a big family and enjoying a happy future. Those dreams have now been shattered. She genuinely believed he loved her. The fact he cheated with her best friend is shocking.''
